Description

  The present invention relates to a winder that winds a collecting wire used for manufacturing a braided wire around a bobbin, a bobbin that winds the collecting wire, and a manufacturing method of a collecting wire bobbin around which the collecting wire is wound.

  For example, in automobiles and electrical equipment, braided wires made by braiding a set of wires in a state in which a plurality of strands are arranged in a line in parallel are often used in places where countermeasures against electromagnetic noise are required. For the production of the braided wire, a braiding machine configured to join the collective wires supplied from the collective wire bobbin at the knitting opening and knit them into a cylindrical shape is used (for example, Patent Document 1).

  The collecting wire bobbin used for the braiding machine is produced by winding the collecting wire around the bobbin using a winder. The winder is configured to send strands from a plurality of strand bobbins, join these strands to form a collective wire, and then wind the collective wire around the bobbin.

JP 2012-238423 A

  In the conventional winder, there is a case where the strands constituting the assembly line intersect or the extra length is generated in some of the strands in the middle of the path from the strand bobbin to the assembly line bobbin. . For this reason, the assembly line wound around the bobbin by the conventional winder often has an intersection of the strands, a surplus length, or the like.

  Since the intersection of the strands in the assembly line is not resolved naturally, if the assembly line is supplied to the braiding machine from the assembly line bobbin produced by a conventional winder, the protrusion resulting from the intersection of the strands in the resulting braiding line Part or deflection may be formed. These protrusions and deflections are not preferable in terms of the quality of the braided wire. Moreover, a braided wire may form a sheath on the outer periphery by inserting a covered electric wire into its cylinder and then extruding it. In this case, if the above-described protruding portion or deflection exists on the braided wire, there is a problem that a hump-like protrusion is formed on the surface of the sheath due to the protruding portion or the like.

  The present invention has been made in view of such a background, and intends to provide a winder capable of suppressing the occurrence of crossing of strands and generation of extra length, a bobbin used in the winder, and a method of manufacturing a collective wire bobbin using the winder. To do.

One aspect of the present invention is a winder for producing a collective wire bobbin in which a collective wire formed by joining a plurality of strands made of metal is wound around a bobbin,
An element supply unit that detachably holds a plurality of element bobbins around which the element is wound;
A merging unit that merges the plurality of strands fed from the strand supply unit to form the aggregated line;
A guide unit that includes at least one guide roller and guides the collective line fed from the merge unit toward the collective line bobbin;
A winding mechanism having a bobbin holding portion that detachably holds the collective wire bobbin, and a drive unit that rotates the collective wire bobbin and winds the collective wire;
It is arranged between the last guide roller closest to the aggregate line bobbin among the guide rollers on the path of the aggregate line and the aggregate line bobbin, and constitutes the aggregate line by passing the aggregate line A strand aligning section for aligning a plurality of strands;
A moving mechanism that moves either the final guide roller or the collective line bobbin relative to the other in a direction parallel to the rotation axis of the collective line bobbin. In the winder.

Another aspect of the present invention is a bobbin for winding a collecting wire using the winder of the above aspect,
A body portion around which the assembly wire is wound;
A pair of flanges provided at both ends of the trunk,
The bobbin is characterized in that the body portion has a multi-threaded spiral groove provided with the same number of grooves as the number of the strands included in the assembly line.

Still another aspect of the present invention uses the winder of the above aspect,
After aligning the plurality of strands constituting the assembly line by passing the assembly line through the strand alignment section between the final guide roller and the assembly line bobbin,
The assembly line bobbin manufacturing method is characterized in that the assembly line is wound around the assembly line bobbin while the alignment state is maintained.

  The winder includes a strand aligning unit that aligns the plurality of strands between the last guide roller and the assembly line bobbin on the assembly line path. Therefore, by passing the assembly line through the element alignment unit, it is possible to realize an alignment state in which the plurality of elements are aligned in a line in parallel.

  Furthermore, the winder has a moving mechanism that moves either the final guide roller or the collective line bobbin relative to the other in a direction parallel to the rotation axis of the collective line bobbin. . Therefore, by reciprocating at least one of the final guide roller or the collective wire bobbin according to the rotational speed of the collective wire bobbin, the collective wire is regularly wound in layers while maintaining the aligned state. can do.

  As described above, the winder further includes the moving mechanism unit in addition to the final guide roller, the assembly wire bobbin, and the strand aligning unit having the specific positional relationship. The assembly line can be regularly wound in layers. As a result, it is possible to effectively suppress the intersection of the strands and the occurrence of extra length in the assembly line.

  Further, the winder can produce the assembly line bobbins with less crossing of the strands and less extra length than in the conventional winder. Therefore, by producing a braided wire using the assembly wire bobbin, the formation of the protruding portion can be suppressed, and the quality of the braided wire can be improved.

  Although a conventionally known bobbin can be used for the winder, the use of the bobbin provided with the spiral groove can more effectively suppress the intersection of the strands and the occurrence of extra length. In other words, the body portion of the bobbin according to the above aspect has a multi-threaded spiral groove having the same number of grooves as the number of the strands included in the assembly line, and thus the body portion directly Each strand to be wound can be wound along the groove. As a result, the position of each wire wound directly around the body portion is regulated, the wires are arranged at equal intervals along the groove portion, and the assembly wire is wound with a uniform height. Can do.

  In addition, since the first layer of the assembly line that is directly wound around the trunk portion by the spiral groove is in a uniform state, the assembly line that is wound in the second layer is also wound in a state of uniform height. can do. Similarly, the assembly line wound around the second and subsequent layers can also be wound on the lower assembly line with a uniform height. As described above, the bobbin according to the aspect described above can regularly wind the assembly line in a layered manner. It can be effectively suppressed.

FIG. 3 is a top view of a final guide roller in the winder of the first embodiment. FIG. 4 is a partial cross-sectional view taken along line IV-IV in FIG. 3.

The partial cross section figure which shows an example of the winding state of the assembly line in the assembly line bobbin produced using the conventional winder. The top view of the bobbin which has a spiral groove in Example 2. FIG. The partial cross section figure which shows an example of the winding state of the assembly line at the time of using the bobbin of Example 2 (The figure corresponded in the VIII-VIII line partial arrow cross section of FIG. 7). In Example 3, the partial expanded side view of the winder which has a baffle plate as a strand alignment part. FIG. 6 is a top view of a current plate in Example 3. FIG. 11 is a sectional view taken along line XI-XI in FIG. 10. FIG. 10 is a top view of a rectifier as a strand aligning unit in the fourth embodiment.

  In the winder, the strand alignment unit may be the final guide roller having a plurality of annular grooves arranged at intervals in a direction parallel to the rotation axis of the assembly wire bobbin. In this case, by passing the strands through the annular groove, it is possible to apply tension to the collective wires and at the same time achieve an aligned state. As a result, the assembly line can be wound around the bobbin while maintaining the aligned state, and as a result, the formation of the protruding portion on the braided line can be effectively suppressed. Moreover, since it is not necessary to separately provide a wire alignment part in the winder, an increase in the number of parts can be suppressed.

  The annular groove may be formed by sinking the surface of the final guide roller, or may be formed between adjacent raised portions by providing a raised portion on the surface of the final guide roller. The cross-sectional shape of the annular groove can be various shapes such as a V shape, a U shape, a rectangle, or a semicircle.

  The final guide roller may have the annular groove having a semicircular cross section with a diameter of 0.08 to 0.5 mm. As the strand used for the braided wire, a metal wire having a diameter of φ 0.08 to 0.5 mm is frequently used. Therefore, the final guide roller having the annular groove having the specific cross-sectional shape can reliably realize the alignment state by passing the strands through the annular groove. As a result, the generation | occurrence | production of the intersection of the strand etc. in an assembly line bobbin can be suppressed more effectively.

  The final guide roller preferably has an interval between adjacent annular grooves of 0.01 to 0.2 mm. When the interval between the annular grooves exceeds 0.2 mm, when passing the assembly line through the final guide roller, the interval between adjacent strands becomes excessively large, which may cause extra length. Note that when the interval between the annular grooves is less than 0.01 mm, the manufacturing cost increases excessively, but it is difficult to obtain an effect commensurate with it.

  Further, the strand aligning portion may be a rectifying plate having a bottom plate portion and a plurality of partition portions erected from the bottom plate portion with a space therebetween. In this case, by passing individual strands between adjacent partition portions, the assembly wire can be wound around the bobbin while maintaining the above-mentioned alignment state, and thus the formation of the protruding portion in the braided wire is effective. Can be suppressed.

  It is preferable that at least the surface of the current plate is made of resin. That is, the rectifying plate may be composed of a metal plate or the like having a resin film formed on the surface, or may be entirely composed of resin. In this case, it is possible to reduce friction between the strand and the current plate when the wire is passed through the current plate. As a result, it is possible to suppress damage to the strands caused by the rectifying plate.

  Moreover, it is preferable that the height of a partition part is 0.5 mm or more. By setting the height of the partition portion to be equal to or larger than the diameter of the strand, it is possible to suppress the strand from floating above the partition portion, and to reliably exert the function of the current plate. As a result, the alignment state can be reliably realized, and the occurrence of the intersection of the strands in the assembly line can be more effectively suppressed.

  The strand alignment unit is a rectifier having a bottom plate portion, a plurality of shaft portions erected from the bottom plate portion spaced apart from each other, and a plurality of partition rollers rotatably supported on the shaft portion. There may be. In this case, by passing the strands between the adjacent partition rollers, the assembly wire can be wound around the bobbin while maintaining the aligned state, as in the case of the rectifying plate. The formation of the portion can be effectively suppressed.

  In the rectifier, since the partition roller is rotatably supported by the shaft portion, friction hardly occurs even if the strand and the partition roller come into contact with each other. Therefore, damage to the strands derived from friction can be suppressed.

  Moreover, when using the bobbin provided with the spiral groove in the winder, it is necessary to use a bobbin in which the number of the groove portions included in the spiral groove matches the number of strands used for the assembly line. For example, when the number of groove portions is larger than the number of strands, a groove portion in which no strands are arranged is generated when the first-layer assembly wire is wound along the spiral groove. In addition, when the number of grooves is less than the number of strands, strands that are arranged out of the trenches are generated. In this way, when the number of grooves and the number of strands do not match, it becomes difficult to wind the assembly wire with the spacing and height of adjacent strands aligned, There is a risk that it will be easy to generate intersections and extra lengths.

  In the bobbin, the groove part preferably has a semicircular cross section having a diameter of 0.08 to 0.5 mm. In this case, similarly to the case of the final guide roller, the wire can be wound along the groove. As a result, the assembly line can be more easily wound regularly in a layered manner, and the occurrence of extra length in the assembly line bobbin can be more effectively suppressed.

  Moreover, it is preferable that the space | interval of the said adjacent groove part is 0.01-0.2 mm. When the interval between the groove portions exceeds 0.2 mm, as in the case of the final guide roller described above, there is a possibility that the interval between adjacent strands becomes excessively large in a state where the assembly wire is wound around the trunk portion. is there. As a result, there is a risk of causing an extra length. Moreover, when the space | interval of an adjacent strand becomes large too much, there exists a possibility that the assembly line which should be wound by the 2nd layer may enter between the strands of the 1st layer depending on the case. In this case, since it becomes difficult to align the heights of the strands, it is difficult to wind the assembly wires in layers. Note that when the interval between the annular grooves is less than 0.01 mm, the manufacturing cost increases excessively, but it is difficult to obtain an effect commensurate with it.

(Example 1)
Examples of the winder will be described with reference to the drawings. As shown in FIGS. 1 and 2, the winder 1 joins a plurality of strands 100 made of metal to form a collective wire 10, and winds the collective wire 10 around a bobbin 7 to produce a collective wire bobbin 11. It is configured to be able to.

  As shown in FIGS. 1 and 2, the winder 1 includes a strand supply unit 2, a junction unit 3, a guide unit 4, a winding mechanism unit 5, a strand alignment unit A, and a moving mechanism unit 6. As shown in FIG. 1, the strand supply part 2 is comprised so that the some strand bobbin 21 by which the strand 100 was wound can be hold | maintained so that attachment or detachment is possible. The merging unit 3 has a function of forming the aggregated wire 10 by merging the plurality of strands 100 sent out from the strand supply unit 2. The guide unit 4 includes at least one guide roller 41 (41 a, 41 b, 41 c, 41 d), and has a function of guiding the collective line 10 sent out from the merge unit 3 toward the collective line bobbin 11.

  The winding mechanism unit 5 includes a bobbin holding unit 51 that detachably holds the collective wire bobbin 11 and a drive unit 52 that rotates the collective wire bobbin 11 and winds the collective wire 10. The strand aligning part A is arranged between the last guide roller 41d closest to the collective line bobbin 11 and the collective line bobbin 11 among the guide rollers 41 on the path of the collective line 10, and passes through the collective line 10 By doing so, it has a function of aligning the plurality of strands 100 constituting the assembly line 10. As shown in FIG. 2, the moving mechanism 6 moves either the final guide roller 41 d or the collective line bobbin 11 relative to the other in a direction parallel to the rotation axis of the collective line bobbin 11. It is configured to be able to.

  Hereinafter, each part of the winder 1 will be described in detail. As shown in FIG. 1, the guide portion 4, the winding mechanism portion 5, the moving mechanism portion 6, and the strand aligning portion A in the winder 1 of this example are fixed to the main body frame 12. Moreover, the strand supply unit 2 and the junction unit 3 are disposed outside the main body frame 12. The strand supply unit 2 is configured such that a plurality of strand bobbins 21 can be attached and detached, and each strand bobbin 21 is rotatably supported by a gantry (not shown). In this example, the strand 100 is pulled out from each of the four strand bobbins 21, and is sent out toward the junction 3 with the rotation of the strand bobbins 21.

  The four strands 100 sent out from the strand bobbin 21 merge at the junction 3 to form a collective wire 10. The merging portion 3 of this example is a pulley having a substantially V-shaped groove (not shown) on the surface, and the four strands 100 pass through the above-described groove to become the assembly line 10.

  As shown in FIG. 1, the assembly line 10 that has passed through the pulley enters the body frame 12 from the upper part of the body frame 12 and is guided toward the assembly line bobbin 11 by the guide portion 4. The guide unit 4 of this example has four guide rollers 41. Three guide rollers 41 a, 41 b, and 41 c on the side of the collective line 10 near the junction 3 are fixed to the upper portion of the main body frame 12 so as to be freely rotatable. These three guide rollers 41a to 41c have a substantially V-shaped groove on the surface in the same manner as the pulley of the merging portion 3, and the collecting wire 10 is guided toward the collecting wire bobbin 11 while passing through this groove. The The collective line 10 that has passed through the three guide rollers 41a to 41c is sent out toward the final guide roller 41d provided below these guide rollers 41a to 41c. In addition, the winder 1 of this example has the disconnection detection apparatus 42 which detects the disconnection of the assembly line 10 between the three guide rollers 41a-41c and the last guide roller 41d.

  The final guide roller 41d is detachably supported by a movable arm 61 (described later) of the moving mechanism unit 6. The movable arm 61 is provided with a through hole (not shown) through which the collective line 10 passes.

  As shown in FIGS. 3 and 4, the final guide roller 41 d has a plurality of annular grooves 411 arranged at intervals in a direction parallel to the rotation axis of the collective line bobbin 11. The number and the cross-sectional shape of the annular groove 411 provided in the final guide roller 41d can be appropriately selected according to the number and diameter of the strands 100 wound around the collective wire bobbin 11. As shown in FIG. 4, the annular groove 411 of this example has a semicircular cross section having a diameter slightly larger than the diameter of the strand 100. Moreover, the space | interval d1 of the adjacent annular groove 411 can be suitably set in the range of 0.01-0.2 mm. The number of annular grooves 411 is selected by preparing in advance a plurality of types of final guide rollers 41d in which the number of annular grooves 411 is changed, and attaching the final guide rollers 41d suitable for the assembly line 10 to be used to the movable arm 61. This can be done easily.

  For example, the winder 1 of this example is configured to wind up the assembly wire 10 composed of four strands 100. Therefore, in this example, the final guide roller 41 d having four annular grooves 411 is attached to the movable arm 61. As a result, as shown in FIG. 4, the strands 100 constituting the assembly line 10 are allowed to pass through the annular grooves 411, and an aligned state in which the four strands 100 are arranged in a row in parallel can be realized. As described above, the final guide roller 41d of this example is configured to function as the strand aligning portion A. The collecting wire 10 that has passed through the final guide roller 41 d is wound around the collecting wire bobbin 11 held by the winding mechanism unit 5.

  As shown in FIGS. 1 and 2, the winding mechanism unit 5 includes a bobbin holding unit 51 that holds the collective line bobbin 11 and a drive unit 52 that rotates the collective line bobbin 11 and winds the collective line 10. Yes. As shown in FIG. 2, the bobbin holding portion 51 of this example has a pair of chucks 511 (511a, 511b) arranged to face each other in a direction (horizontal direction) parallel to the rotation axis of the collective line bobbin 11. ing. Each chuck 511 is configured to be movable in a direction parallel to the rotation axis of the collective wire bobbin 11. Thereby, the space | interval between chuck | zipper 511 can be adjusted freely. The drive unit 52 includes a motor 521 and an annular belt 522, and the rotation of the motor 521 is configured to be transmitted to one chuck 511 a of the pair of chucks 511 via the annular belt 522.

  The winding mechanism unit 5 of this example can wind the collecting wire 10 around the bobbin 7 as follows. First, the bobbin 7 is disposed between the pair of chucks 511, and then the interval between the pair of chucks 511 is narrowed, so that the bobbin 7 is brought into contact with the chucks 511 as shown in FIG. Hold it. When the motor 521 is rotated in this state, the rotation of the motor 521 is transmitted to the bobbin 7 through the annular belt 522 and one chuck 511a. As described above, the bobbin 7 can be rotated to wind up the collecting wire 10.

  As shown in FIG. 2, the moving mechanism unit 6 of this example includes a movable arm 61 that supports the final guide roller 41 d, a control unit 62 provided on the main body frame 12, and a direction parallel to the rotation axis of the collective line bobbin 11. Two shafts 63 extending from the control unit 62 and a shaft support arm 64 that supports the shaft 63 are provided. The moving mechanism unit 6 is configured to reciprocate the shaft 63 in a direction parallel to the rotation axis of the collective line bobbin 11, and to reciprocate the final guide roller 41d accordingly.

  The control unit 62 has a front surface portion 621 provided along the longitudinal direction of the two shafts 63 and a side surface portion 622 that supports the one end 631 side of the two shafts 63, as shown in FIG. It has a substantially L shape in a top view. A shaft support arm 64 that supports the other end 632 side of the shaft 63 and a chuck support arm 65 that rotatably supports the other chuck 511 b of the pair of chucks 511 are extended from the front surface portion 621.

  One chuck 511 a is accommodated in the side surface portion 622, and the annular belt 522 and one chuck 511 a are engaged in the inside of the side surface portion 622. The side surface portion 622 has a drive mechanism (not shown) for moving the shaft 63 in a direction parallel to the rotation axis of the collective line bobbin 11.

  The two shafts 63 are arranged side by side in the horizontal direction, and are supported at two portions of the side surface portion 622 and the shaft support arm 64. A movable arm 61 is fixed between the side surface portion 622 and the shaft support arm 64 of the two shafts 63. Accordingly, the movable arm 61 and the final guide roller 41d supported by the movable arm 61 can be moved in a direction parallel to the rotation axis with respect to the collective line bobbin 11 as the shaft 63 reciprocates.

  Next, the function and effect of this example will be described. The winder 1 includes a final guide roller 41d as a strand alignment unit A that aligns the plurality of strands 100 between the final guide roller 41d and the assembly line bobbin 11 on the path of the assembly line 10. Therefore, as shown in FIG. 4, by passing the strands 100 constituting the assembly line 10 through the annular groove 411 of the final guide roller 41d, an alignment state in which a plurality of strands 100 are aligned in a line in parallel is realized. can do.

  Further, the winder 1 has a moving mechanism unit 6 that moves the final guide roller 41d relative to the collecting line bobbin 11 in a direction parallel to the rotation axis thereof. Therefore, the assembled wires 10 in the aligned state can be regularly wound in layers. That is, the winder 1 of the present example can freely adjust the pitch when the collecting wire 10 is wound spirally by reciprocating the final guide roller 41d according to the rotation of the collecting wire bobbin 11. . For example, by setting the pitch so that the final guide roller 41d moves by the same length as the width of the collective line 10 during one rotation of the bobbin 7, the collective line 10 is wound without a gap as shown in FIG. can do.

  Further, by appropriately setting the pitch at the time of winding the collective line 10, as shown in FIG. 5, the first-layer collective line 10a has a uniform height. Therefore, the collecting wire 10b wound in the second layer can also be wound in a state where the heights are uniform. Similarly, the assembly line 10 wound after the second layer can also be wound on the lower assembly line 10 in a state of uniform height.

  On the other hand, since it is difficult for the conventional winder 1 to be wound around the collecting wire bobbin 11 while maintaining the aligned state of the collecting wire 10, for example, as shown in FIG. 6, the collecting wire 10 a wound around the bobbin 7 Protruding portions 101 derived from the intersections and extra lengths of the strands 100 are easily formed. And if the protrusion part 101 is formed, it will become easy to collapse the alignment state of the assembly line 10b wound on it, and it will become difficult to wind it regularly in layers. As a result, further crossing of the strands 100 and generation of extra length are caused.

  As described above, the winder 1 includes the final guide roller 41d, the collecting wire bobbin 11, and the strand aligning portion A having the specific positional relationship, and further includes the moving mechanism portion 6, so The wire 10 can be regularly wound in layers. As a result, it is possible to effectively suppress the crossing of the strands 100 and the occurrence of extra length.

  Further, the winder 1 can produce the assembly line bobbin 11 with less crossing of the strands 100 and less surplus length than in the prior art. Therefore, by forming the braided wire using the assembly wire bobbin 11, the formation of the protruding portion 101 can be suppressed, and the quality of the braided wire can be improved.

  In this example, an example of the winder 1 having the moving mechanism unit 6 configured to move the final guide roller 41d is shown, but the moving mechanism unit 6 is configured to move the collective line bobbin 11. May be. As the moving mechanism unit 6, a mechanism similar to a conventionally known traverse device can be used.

(Example 2)
This example is an example of the bobbin 7b that winds up the collecting wire 10. 7 and 8 show an example of a bobbin 7b configured to wind up the assembly wire 10 composed of four strands 100. FIG. Of the reference numerals used in FIGS. 7 and 8, the same reference numerals as those used in the first embodiment denote the same components as in the first embodiment unless otherwise specified.

  As shown in FIG. 7, the bobbin 7 b has a columnar body 71 around which the assembly line 10 is wound, and a pair of flanges 72 provided at both ends of the body 71. Further, as shown in FIGS. 7 and 8, the body portion 71 has four spiral grooves 73 provided with groove portions 731 having the same number as the number of the strands 100 included in the assembly line 10.

  The cross-sectional shape of the groove 731 provided in the final guide roller 41d can be appropriately selected according to the number and diameter of the strands 100 wound around the bobbin 7b. For example, the groove portion 731 of this example has a semicircular cross section having a diameter slightly larger than the diameter of the strand 100. Moreover, the distance d2 between the adjacent groove portions 731 can be set as appropriate within a range of 0.01 to 0.2 mm.

  For example, the bobbin 7b of this example is attached to the bobbin holding portion 51 in the winder 1 of the first embodiment and winds the assembly wire 10 to thereby more effectively suppress the occurrence of the crossing of the strands 100 and the extra length. be able to. That is, since the bobbin 7b has four spiral grooves 73 having the same number of grooves 731 as the number of the strands 100 included in the assembly line 10, as shown in FIG. The wire 100 to be wound can be wound along each groove portion 731. As a result, the positions of the strands 100 wound directly around the body portion 71 are regulated, the strands 100 are arranged at equal intervals along the groove portion 731, and the first-layer assembly wires 10a are aligned in height. It can be wound with.

  Moreover, since the first-layer assembly line 10a is in a uniform state by the spiral groove 73, the assembly line 10b wound in the second layer can also be wound in a uniform state. Similarly, the assembly line 10 wound after the second layer can be wound on the lower assembly line 10 in a uniform state. As described above, since the bobbin 7b can wind the assembly wire 10 regularly in a layered manner, it is possible to effectively prevent the crossing of the strands 100, the occurrence of extra length, and the like caused by the difference in the winding height. Can be suppressed.

(Example 3)
This example is an example of the winder 1 having the baffle plate 66 as the strand alignment part A. As shown in FIG. 9, the rectifying plate 66 of this example is detachably attached to a stay 611 extending from the movable arm 61 and is disposed on the path of the collective line 10. Note that the final guide roller 41d in this example does not have the annular groove 411, and has a cylindrical shape with a smooth surface.

  As shown in FIGS. 10 to 11, the rectifying plate 66 includes a bottom plate portion 661 and a plurality of partition portions 662 that are erected from the bottom plate portion 661 with a space therebetween. The rectifying plate 66 achieves an aligned state in which a plurality of strands 100 are aligned in parallel with each other by passing individual strands 100 constituting the assembly line 10 between adjacent partition portions 662. it can. 10 and 11 show an example of the rectifying plate 66 having four strands 100 constituting the assembly line 10 and having five partition portions 662, the number of the partition portions 662 is as follows. It can be appropriately changed according to the number of the strands 100. As with the final guide roller 41d in the first embodiment, the number of the partitioning portions 662 is selected in advance by preparing a plurality of types of rectifying plates 66 in which the number of the partitioning portions 662 is changed, and rectification suitable for the aggregate line 10 to be used. This can be done easily by attaching the plate 66 to the stay 611. Others are the same as in the first embodiment. Of the reference numerals used in FIGS. 9 to 11, the same reference numerals as those used in the first embodiment are the same as those in the first embodiment unless otherwise specified.

  As shown in FIG. 9, the current plate 66 of this example is disposed between the final guide roller 41 d and the collective line bobbin 11 on the path of the collective line 10. Therefore, the assembly line 10 that has passed through the current plate 66 can be wound around the assembly line bobbin 11 while maintaining the aligned state. As a result, the assembly wire 10 can be wound in layers, and the same effects as those of the first embodiment can be achieved.

Example 4
This example is an example of the rectifier 67 used in the wire alignment part A. As illustrated in FIG. 12, the rectifier 67 includes a bottom plate portion 671, a plurality of shaft portions 672 that are erected from the bottom plate portion 671 at intervals, and a plurality of partition rollers that are rotatably supported by the shaft portion 672. 673. The rectifier 67 can be used by being attached to the stay 611 of the movable arm 61 as in the third embodiment.

  The rectifier 67 of this example is configured to pass one strand 100 between a pair of partition rollers 673. That is, as shown in FIG. 12, when the number of the strands 100 which comprise the assembly line 10 is four, the number of the partition rollers 673 provided in the rectifier 67 is four pairs. Others are the same as in the third embodiment. Of the reference numerals used in FIG. 12, the same reference numerals as those used in the third embodiment denote the same components as in the third embodiment unless otherwise specified.

  As described above, even if the rectifier 67 is used instead of the rectifying plate 66 as the strand aligning portion A, the assembly wire 10 can be regularly wound in layers while maintaining the aligned state, and the same as in the third embodiment. The effect of this can be achieved. Moreover, since the partition roller 673 is rotatably supported by the shaft portion 672, the rectifier 67 is less likely to be frictional even if the wire 100 and the partition roller 673 come into contact with each other. Therefore, damage to the strand 100 can be effectively prevented.
